"Larkey Natural Selection: Computer Simulation"
Bellwork:
1) True or false?: recessive alleles have more influence on an organism’s traits.
2) A gene will increase in a population if it is ______________ for the organisms.
3) Puppies of a Ww (white) dog and a ww (black) dog will have ________________ -colored fur.
- Review Wed/Thurs activity
- Complete larkey "natural selection" simulation from FOSS Media Website (username: cheetah, password: 112)
- Complete workbook page 129: record computer simulation data and answer analysis questions
- Notes:
Adaptations in the forest and the prairie are different ==> different adaptations help the larkeys survive in these 2 different environments.
Over time, particular traits disappear because they are unhelpful (the larkeys with these traits get eaten and can't pass them on). Other traits increase because they are adaptations - these larkeys survive, reproduce, and pass on their traits so they don't go extinct.

"Larkeys and Natural Selection: Moving to a New Environment"
Bellwork:
1) New species evolve because of ___________, selective pressure, and isolation.
Hint: the word starts with a V
2) Why would one gene increase if an environment changed?
3) Draw the Punnett square for parents TT and Tt.
- "Voyage to the Galapagos": Examples of Natural Selection in action
1) Darwin's finches: they live on different islands, so different adaptations helped them survive - the surviving birds looked different in different environments, and they eventually got different enough to be different species
2) Marine iguanas: small size is an adaptation on islands with less food - if they were big, they'd starve to death; small iguanas survived and passed on genes for small size
3) Masked boobies: they kill their younger siblings; the second chick is a back-up in case the 1st doesn't hatch, and a surviving 1st chick will kill the 2nd chick to make sure he gets enough food
- Look at this site for a cyber field trip to the Galapagos Islands
- Larkey simulation: complete pages 119, 121, and 123 in the yellow workbook
